If we believe the first form of life occurred on the sea floor, why shouldn't we believe that new forms of life are spontaneously occurring on the sea floor all the time?
Once a cell has formed, through the miracle of exponential growth its descendants will quickly suck up available nutrients until you run out of some key nutrient, and then it can never happen again.
Suppose that that formation of a viable cell was a 1 in a million year event. It would be essentially inevitable over a hundred million years. But the time from happening once to impossible is a lot, lot, lot less than a million years...
